Wildcard certificates have become a popular choice for websites who need to protect multiple domains and subdomains. They are quick to deploy and save money for businesses compared to buying individual SSL certificates. They do come with some risks, which must be carefully addressed.
Wildcard Certificates Have Risks
Wildcard TLS certificates provide security for all domains and subdomains on a single server. This is a great choice for organizations with multiple websites that need to use HTTPS, but it comes with some significant security issues.
The biggest security risk of wildcard certificates is that if a single server or subdomain is compromised, all other servers and subdomains may be at risk. It is possible to launch phishing campaigns against other subdomains using the same certificate if a single server or subdomain is compromised.
If the wildcard cert is revoked then all subdomains must be issued with a brand new certificate. It is a huge amount of work which can cause a site or service to be down for a long time.
This could lead to traffic redirections if the wildcard certificate's private key is compromised. This is called an Application Layer Protocol Allowing Cross-Protocol Attack (ALPACA).
An attacker with network access who is malicious can exploit this vulnerability and steal sensitive data, such as passwords and credit cards. The NSA warns organizations against this danger and suggests they should not use TLS wildcard certificates in their infrastructure.
What is a Wildcard Certificate?
A wildcard SSL/TLS is a digital certificate that protects all subdomains within a specific domain. It's issued by a Certificate Authority. Most browsers and smartphones support it.
This certificate can be used to secure unlimited servers. The certificate can be used for securing a number of subdomains and domains at the same time.
They are more secure than other options for securing websites. They are easier to use and more reliable than multi-domain certificates. They are compatible with modern devices and web browsers.
In most cases they are a good option for organisations that need to secure a large number or domains. They are the best option for organizations that need to protect a large number of domains or subdomains at once.
There are several different kinds of wildcards available. All wildcard certificates offer the same features, but their prices differ. Some CAs, such as VeriSign, will price wildcard certificates by the domain being protected, while others will price them based on the total number of domains they are protecting.
Wildcard certificates are a good choice for organizations that want to protect several domains and subdomains. The purpose of a Wildcard Certificate should be discussed with the Security Team and Leadership to make sure that the implementation is in the best interest of the company.
